Besides the Arabic chronicles of Abulfeda, Elmacin, and Abulpharagius, under the seventy-third year of the Hegira, we may consult D'Herbelot (Biblioth. Orient. p. 7) and Ockley (Hist. of the Saracens, vol. ii. p. 339-349). The latter has given the last and pathetic dialogue between Abdallah and his mother, but he has forgot a physical effect of her grief for his death, the return, at the age of ninety, and fatal consequences of her menses.
